RU2470121C2 - Method of water supply to city - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: method consists in delivery of water to individual users connected to a settlement water supply system, via manifold and distributing lines of a water supply network, and further via house or street distributors. Along manifold lines (1) combustible gas hydrogen or natural gas used for domestic purposes is supplied. Water is received upstream distributing lines (5) by burning of combustible gas with further cooling of produced gases, also in local centralised heating points (2), serving for heating of premises (6), and condensation of produced water vapours upstream distributing lines (5) of a water supply network. In case of necessity condensed water is sent via systems or filters of treatment arranged in these local points or in premises of water reception.

EFFECT: invention provides for simplicity and reliability of water supply.

Description

According to the International Patent Classification (IPC) in the 2011 edition (2011.01), the city’s water supply method relates to water supply methods (Е03В 1/00), and in particular to methods for extracting or collecting drinking or tap water (Е03В 3/00), including parts of devices (Е03В 3/40), and therefore the methods used to extract water, more precisely the generation or production of water for water supply of settlements.

A known method of supplying water from reservoirs for water supply to settlements (RF Patent No. 2400599, IPC EV03 / 02 (2006.01), publ. 09/27/2010). It lies in the fact that the water supply system is performed in the form of interconnected vertical and inclined pipelines. The lower end of the vertical pipeline is installed in a reservoir for water withdrawal, and the upper is connected to the upper end of the inclined pipeline. Water is lifted up using a booster system.

The disadvantage of this method is that it uses large energy costs required to raise the water to the level necessary to move it through the pipelines. And, in addition, the design of the piping system is cumbersome due to the need to pump large masses of water over long distances.

There is a known method of water supply and a system for its implementation (RF Patent No. 2348763, IPC EV03 1/04 (2006.01), publ. 10.03.2009). The method consists in delivering water to individual users connected to the water supply system of the settlement through the main and distribution lines of the water supply network, and then through the house inlets and street water intakes (columns). The known method involves long trunk and distribution lines of the water supply network from a water source, and therefore, high energy costs for pumping water through them.

The technical result of the new method of water supply in the city is to reduce the size of the water supply system and reduce the costs of both building this system and its operation.

This result is achieved by the fact that in the new method of water supply in the city, which consists in delivering water to individual users connected to the water supply system of a settlement through the main and distribution lines of the water supply network, and then through house or street distributors.

What is new in it is that hydrogen or natural gas used in households are supplied with flammable gas through the main lines, and water is obtained in front of the distribution lines by burning combustible gas with subsequent cooling of the generated gases, including in local centralized heating centers serving for heating premises, and condensation of the generated water vapor in front of the distribution lines of the water supply network with the passage of condensed water, if necessary, through the cleaning systems or filters located in these locks lnny points or in premises of receiving water.

The drawing shows a diagram of the implementation of the new method. The main pipes 1 supply combustible gas to one of the local centralized heat points 2, where it is burned with access to atmospheric air. Waste gases in the form of carbon dioxide (carbon dioxide), water vapor and non-combustible nitrogen pass through the central heating pipes of 3 buildings and premises. Then in the freezer 4 water vapor condenses and enters the distribution lines 5 of the water supply network of buildings and premises 6.

The above technical result is a reduction in the size of the water supply system and a decrease in both the construction of this system and its operation due to the refusal to pump over long distances (tens or even hundreds of kilometers) of a large mass of water from rivers and reservoirs.

Claims (1)

The city’s water supply method, which consists in delivering water to individual users connected to the settlement’s water supply system through the main and distribution lines of the water supply network, and then through house or street dispensers, characterized in that hydrogen or natural gas used in the main lines supply combustible gas household, and water is obtained in front of the distribution lines by burning combustible gas with subsequent cooling of the formed gases, including in local centralized heat nktah serving for heating, and water formed by condensation of vapor prior to distributing the lines passing water network with the condensed water, if necessary, through a purification system or filters located in these local points or smokers produce water.
